02/18/2013 (08:00PM - 10:01PM) (Monday) : PLAYERS WORK TOGETHER FOR CHANCE TO WIN IMMUNITY FOR ALL -- The Players learn they'll have the chance to win immunity for all this week if they lost a collective 70 pounds. They have a chance to shave 10 pounds off their total with the help of returning kid participants Biingo, Lindsay and Sunny, whose brains and brawn are tested in a pop challenge. With emotions and tensions at an all-time high, this week's theme of "working together" might be a tougher challenge than losing the amount of weight that will keep them all safe for another week. Two contestants clash, as do Jillian and one of The Players that she feels is not performing at the level she should be. But all the contestants will have to work together in an exhaustive sand-digging challenge that could give them another weigh-in advantage. And the trainers and players participate together in an intense team-building challenge, forcing them all to rely on and trust one another. Also this week, Subway's Jared stops by for lunch and a pep talk, and Jillian and the kids sign Seventeen's "Body Peace Treaty," encouraging self-esteem and body acceptance, before a tension-filled weigh-in reveals whether they'll all be safe - or have to send another player home.
